The vacuum oven reading of the vacuum gauge reflects a number of Pa. Can you use an intuitive digital display?
(1) A "0" on the vacuum gauge expresses a pressure of a large atmosphere, and "-0.1" expresses a complete vacuum. The finger on the vacuum gauge does not express the full value of the vacuum, only the relative value of the vacuum is expressed.
Conversion of vacuum degree; according to the scale indication range of this table, the complete value and relative value of vacuum degree can be converted by the following formula:
P=1×105 (1-δ/0.1) P - complete value of vacuum (Pa)
The value of the scale of the δ-vacuum table is the full value
Example 1: The indication value of the table is O, then P=1×105(1-O/0.1)=1×105 Pa = 1 large atmospheric pressure
Example 2: The indicated value of the table is 0.1, then P = 1 × 105 (1 - 0.1 / 0.1) = 0 Pa is a complete vacuum.
(complete vacuum does not exist)
Example 3: The indication value of the table is 0.08, then P=1×105(1-0.08/0.1)=2×104Pa
The vacuum index value of this product is <267Pa, which can guarantee normal office work under the condition of low vacuum when the product is 267Pa (external value is about 0.0197, nearly -0.1). The degree of vacuum of the product is mainly determined by the performance of a set of air extractors.
The vacuum unit of measure is converted as follows:
0.1Mpa =1×105 Pa = 760mmHg = 1 large atmospheric pressure
1乇= 1mmHg =133.33Pa
2乇= 0.00026666Mpa≈267Pa (2) Vacuum gauge readings can be revealed with an intuitive digital display. However, the price is extremely expensive, and it is generally suitable for use in scientific research units.

The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
